当然不行了，具体参考《windows程序设计》
----------------------------------
GetStockObject(BLACK_PEN)获取黑色画笔
GetStockObject(GRAY_PEN)获取中灰色画笔
......
GetStockObject(NULL_PEN)获取空的画笔
pDC->SelectObject(::GetStockObject(NULL_PEN));把获取的空的画笔选入DC
----------------------------------
GetStockObject(BLACK_PEN)获取黑色画笔
GetStockObject(GRAY_PEN)获取中灰色画笔
......
GetStockObject(NULL_PEN)获取空的画笔
pDC->SelectObject(::GetStockObject(NULL_PEN));把获取的空的画笔选入DC

CDC::SelectObject
This method selects an object into the device context. The CDC class provides five Windows CE implementations specialized for particular kinds of GDI objects, including pens, brushes, fonts, bitmaps, and regions. The newly selected object replaces the previous object of the same type.
The GetStockObject function retrieves a handle to one of the stock pens, brushes, fonts, or palettes
